Return point-wise k nearest neighbor
nearest_neighbors(distance_matrix, k)
| distance_matrix | A distance matrix |
|---|---|
| k | An integer or sequence of integers specifying the desired nearest neighbors |
An N x k tibble with ordered pairwise distances
A distance matrix (either a full square matrix or a "dist" object) is required as input.
